Proactive engagement with our portfolio

Sustainability pathway

During our ownership, we use our influence to encourage our portfolio companies to enhance their ESG maturity and make progress from their respective positions along our Sustainability pathway. 

We support portfolio companies with a bespoke approach for each, depending on the sustainability-related issues each faces. Our portfolio companies made good progress this year.

3i Sustainability connections - leveraging our network to support change

We offer our portfolio companies the opportunity to harness a diverse array of knowledge and expertise from across the entire portfolio.


Throughout the year, our portfolio wide engagement featured a series of webinars aimed at facilitating the exchange of best practices. The webinars were tailored to address the evolving needs of our portfolio companies, covering a diverse range of topics such as climate change fundamentals, navigating upcoming European Corporate Sustainability Reporting Directive regulations, cyber security, and strategies for enhancing workforce diversity. Invitations were extended to the designated individuals responsible for ESG within the portfolio companies and each webinar comprised presentations from expert speakers alongside real life success stories drawn from the portfolio.

Sustainability Forum

In February 2024 we held our first Sustainability Forum. This event brought together over 35 participants from 21 companies across 3i’s portfolio, including representatives from 10 out of 12 of the 3i Infrastructure companies. 

The interactive sessions delved into various topics material to our portfolio’s success. These included setting a winning Sustainability strategy, readiness for CSRD compliance, insights into setting science-based emissions reduction targets, and perspectives on the 2023 UN Climate Change Conference. Additionally, participants took part in a workshop on value-led decarbonisation and a gamified session involving a board decision based on financial, environmental and social factors. The event was supported by third-party experts and featured numerous short presentations from portfolio companies showcasing best practices.



We support our portfolio companies to become more mature in their sustainability efforts and invest in decarbonisation challenges. Find out how.
